摘　　要：针对攀西地区钛铁矿的特点即储量大、品位低、钙镁杂质含量高,提出钛铁矿湿法生产人造金红石的新工艺:钛铁矿细磨-多级逆流浸出。解决了盐酸再生与再生酸循环利用的衔接问题。采用低浓度盐酸多级浸出可得到TiO2品位大于94%的人造金红石产品。The high-grade artificial rutile preparation technolgy from ilmenite of Panzhihua area by fine grindingmultistage countercurrent leaching at normal pressure is investigated based on the characteristic of the ilmenite such as large reserves, low grade and high-content of calcium and magnesium. The problem of hydrochloric acid regeneration and recycling is solved. The results show that the grade of TiO2 is over 94% by multilevel counterflow leaching with hydrochloric acid.
